Patented Oct. 22, 1929 ATENT ()FFICE JOHN KRUMHOLZ, OF MINEOLA, NEW YORK ROOF BRACKET Application filed July 31, 1928. Serial No. 296,438.

This invention relates to a roof bracket, and has for its ob ect to provide, 111 a manner as hereinafter set forth, a bracket of such class constructed and arranged to enable one to expeditiously build a scaffold on a slanting roof and with the brackets and cross boards of the scaffold detach ably and firmly held in position relatively to each other without the employment of bolts, screws and nails.

A further object of the invention is to provide, in a manner as hereinafter set forth, a roof bracket formed of a plurality of sections having coacting interengaging means for detachably connecting them together, and further including means for retaining and upporting a scaffold cross board or run board transversely thereof.

Further objects of-the invention are to provide, in a manner as hereinafter set forth, a roof bracket which is simple in its construc tion and arrangement, strong, durable, compact, thoroughly efiicient in its use, expeditiously positioned with respect to a roof, thoroughly efficient in its use, and comparatively inexpensive to manufacture.

YVith the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters corresponding parts denote throughout the several views:

Figure 1 is a fragmentary view in elevation of a structure showing the adaptation with the roof thereof of a roof bracket in accordance with this invention.

Figure 2 is a fragmentary view in plan, of two of the brackets having a cross board or run board detachably supported thereby.

Figure 3 is a perspective view, broken away, of a lower section of the bracket.

Figure l is a fragmentary view, in perspective and broken away of a top section of the bracket.

A roof bracket, in accordance with this invention includes a top or upper section and one or more bottom or lower sections. Each of the sections of the bracket can be of any desirable length. v

The top section is indicated generally at 1 and which comprises a flat bar 2 torsionally twisted, intermediate its ends, as at 2 to provide an upper part 3 disposed at right angles with respect to the lower part 4 of the bar 2. The twist in the bar '2 positions the upper part 3 thereof substantially at the longitudinal median of the lower part 4:. The free or upper end of the part 3 of the bar 2 is bent to provide a hook-shaped terminal 5 for the purpose of connecting the section 1 to that side 6 of the roof of the structure 7 opposite the side 8 upon which the bracket is positioned. The lower part 4 0f the bar 2 has secured to its outer face, by the holdfast devices 9 the lower arm 10 of a Z-iron 11. The upper arm of the iron 11 is indicated at 12 and intermediate arm at 13. The arms 10 and 12 are disposed in parallel planes and further in parallelism to the part 4-. The arm 18 is disposed at right ang es with respect to the part l to offset the arm 12 relative to said part. The arms 12, 13 and the part 4 coact to provide a socket 14 for a scaffold cross board or run board 15. The part 4 below the iron 11 has projecting from its outer face a plurality of spaced headed studs 16 and said part 4 in proximity to its lower end has one side edge formed with a notch 17 which is positioned below the lowermost stud 16. 'The purpose of the studs 16 and notch 17 will be presently referred to.

The bracket is illustrated, by way of example, as set up with two lower sections each referred to generally at 18 and as the lower sections are of like construction, but one will be described as the description of one will apply to the other. Eachlower section comprises a fiat bar 19 of substantial length and of a width corresponding to the width of the part 4 of the section 1. The bar 19 in the upper portion thereof is formed with a plurality of spaced key-hole shaped openings 20, one arranged above the other, and pivotally connected to said bar 19, in proximity with a right angularly disposed nose one side edge of the bar 19 in proximity to the latch 21 is formed With a notch 23 to receive the nose 22 when a section 18 is detachahly connected to the section 1. l Vhen a section 18 is connected to the section 1, the notch 17 of the section 1 registers with the notch 23 of the section 18 and the nose 22 of the latch 21 enters the aligning notches to prevent lengthwise shifting of the sections relatively to each other. Further the headed stu of the section 1 are adapted to extend the openings 20 in the bar 19.

Secured to the outer face of the bar 19, by the holdfast devices 2% is the lower rm 25 of a Z-shaped iron 26. 'ihe upper in of the iron 26 is indicated at 27 and the intermediate arm at 28. The arms 25 and 23' e in parallel planes and further are or in parallelism to the bar 19. The

extends at right angles to the bar 19 and oilsets the arm 27 relative to said bar and the tion 18 and the notch 32 of an upper section 18'registers with the notch 23 in a lower section.

vVhen two or more brackets are employed for scaffolding across a roof, the'hrackets are arranged in parallelism or spaced from each other, that is to say the sections of one bracket are arranged in parallel spaced relation with respect to the sections of an adja rt bracket and with the iron 11 of one section 1 arranged in parallelism with respect the iron 11 of an adjacent section 1, and the arrangement is had relative to the iron 2o of one or more lower sections 18 of a plurality of brackets.

Preferably the lower section or sections 18 are 0t greater length than the upper section 1, but the length of the sections of the brackets can he as desired. W hen shinglin a roof there will he SUlllCiQllt clearances to push shingles underneath the brackets. Vi hcn the sections of the bracket are detachably connected together, the upper end of a lower section is mounted upon the lower end of an upper section. The stuns and key-hole shaped openings, in connection with the latches 21 and notches provide means for latching the sections of the bracket together whereby they cannot shift laterally or longitudinally with respect to each other.

It is thought the many advantages of a roof bracket, in accordance with this inven- .tion, can be readily understood, and althon 'h the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which fall within the scope of the invention as claimed.
